<p>CTL element list container</p>
<p>This is a list of CTL elements. The list contains management information (e.g. how many elements the sound card has) as well as the element identifiers. All functions which operate on the list are named snd_ctl_elem_list_*().</p>
<dl class="section user"><dt>Memory management</dt><dd></dd></dl>
<p>There are two memory areas to deal with: The list container itself and the memory for the element identifiers.</p>
<p>To manage the area for the list container, the following functions are used:</p>
<ul>

<p>This comparison ignores the numid part. The numid comparison can be easily implemented using <a class="el" href="group___control.html#ga543f3de35c42f53f2ec2d24217fd4a43" title="Get numeric identifier from a CTL element identifier.">snd_ctl_elem_id_get_numid()</a> calls.</p>
<p>The identifier set fields are compared in this order: interface, device, subdevice, name, index.</p>
<p>The return value can be used for sorting like qsort(). It gives persistent results. </p>
